2. Description of Prior Arts
Memory cards are known in the art and contain intelligence in the form of a memory circuit or other electronic program. Some form of card reader reads the information or memory stored on the card. Memory cards are used in many applications in today's electronic society, including video cameras, music players, ATMs, cable television decoders, toys, games, PC adapters and other electronic applications. A typical memory card includes a contact or terminal array for connection through an electrical connector to a card reader system and then to external equipment. The connector readily accommodates insertion and removal of the card to provide quick access to the information and program on the card. The card connector includes terminals for yieldably engaging the contact or terminal array of the card. Additionally, the connector always has an ejecting mechanism for ejecting the insertion card out.
The prior art discloses a card connector having an insulating housing and a metal shell covering on the insulating housing. The metal shell is constructed as an L shape, and the insulating housing has a triangular plate to guide an L-shape card inserted. On one side of the card connector, an ejecting mechanism is mounted. The ejecting mechanism primarily includes a pushing bar allowing a user to operate, an ejecting bar for pushing a card, and a connecting bar connecting the pushing bar and the ejecting bar for transmitting a force between the pushing bar and the ejecting bar.
However, such card connector is mounted in an electronic equipment, and the connecting bar is fitted on the triangular plate. Therefore, overall height of the card connector is increased. Accordingly, more internal space of the electronic equipment is occupied.
In another prior art, a card connector has an L-shape shell defining a wider portion allowing a card to fit/eject and a narrower portion opposite to the wider portion, an insulating housing receiving a plurality of terminals, an arm portion located on a lateral side of the insulating housing, and an ejecting mechanism mounted on the arm portion. Although the overall height of the card connector is reduced, additional module of the arm portion for coupling with the ejecting mechanism makes a high cost for a producer and, moreover, an assembly process of the card connector becomes more inconvenient.
Therefore, the present invention is directed to solving these various problems by providing a card connector which reduces the overall size of the connector and achieves a lower cost connector.
An object, therefore, of the invention is to provide a card connector reduced a overall size and cost.
In the exemplary embodiment of the invention, A card connector includes an insulating housing, a metal shell, a plurality of terminals and an ejecting mechanism. The insulating housing includes a base section, a base seat extending from one side of the base section, and a guiding portion extending forwardly from the base seat. The metal shell is mounted on the insulating housing to define a card receiving space. The terminals are retained in the base section and protrude into the receiving space. The ejecting mechanism includes an ejecting member protruding into the receiving space, a spring member for moving the ejecting member towards an ejecting direction of the card, a heart groove fitted on the ejecting member, and a latch member for holding the ejecting member in position. Wherein the ejecting mechanism is mounted in a sliding groove formed on the base seat, and the ejecting member is capable of sliding in the sliding groove.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
As shown in
The first shell 11, approximately a rectangular shape in a top plan view, and an U shape in a front view, comprises a first top wall 12, and a pair of first lateral walls 13 extending downwardly from the first top wall 12. The first receiving space 14 is defined by the first top wall 12 associating with the first lateral walls 13 and is divided into an L-shape card slot 140 to receive the first card A and a rectangular space 141, as shown in
The base seat 33, designed approximately in a rectangular shape and longer than the base section 31 along the insertion direction of the card, has a first sliding groove 330 and a second sliding groove 331 perpendicular to the first sliding groove 330. The first sliding groove 330 and the second sliding groove 331, respectively, have a post 333, 335 at one end thereof, and a position hole 334, 336 opposite to corresponding post 333, 335. Particularly, the first sliding groove 330 and the second sliding groove 331 has a first sliding channel 332 and a second sliding channel 337, respectively. The first sliding channel 332 is formed at one edge of the first sliding groove 330, and the second sliding channel 337 is formed at the bottom of the second sliding groove 331 to communicating with the second receiving space 220. Moreover, in this embodiment of the present invention, the base section 31 has a triangular guiding portion 34 extending from the base seat 33 integrally to guide different card inserting. Therefore, the base section 31, the base seat 33, and the guiding portion 34 are integral.
As shown in
The second shell 21 is approximately rectangular shape, and comprises a second top wall 210, a pair of second side walls 211 extending downwardly from opposite sides of the top wall 210. The second top wall 210 has a fixing hole 212 in alignment with the terminal module 23, and a longitudinal groove 213 in accordance with the second sliding channel 337 of the second guiding groove 331.
The bottom plate 22 is constructed according with the second shell 21, and comprises a recess 221 to receiving the terminal module 23. In the terminal module 23, a plurality of second terminals 24 are retained and protrudes upwardly into the second card slot 220 to engage with the second card B electrically.
The relationship between the first ejecting mechanism 6, the second ejecting mechanism 5 and the first groove 330, the second groove 331 will be described in detail. The first ejecting mechanism 6 is mounted in the first groove 330 with the first pushing portion 64 protruding into the card slot 140, one end of the spring member 62 connecting the ejecting member 60 and the other aligned with the post 333, one end of the latch member 61 slipping in the heart groove 63 and the other end placed in the position hole 334. The second ejecting mechanism 5 is mounted in the second groove 331 in the same way as described of the first ejecting mechanism 6, except the second pushing portion 54 protruding downwardly into the second receiving space 220 by going through the second sliding channel 337 and the longitudinal groove 213 of the second metal shell 21, as shown in
According with present invention, the first ejecting mechanism 6 and the second mechanism 5 are mounted in the first sliding groove 330 and the second sliding groove 331, more particularly, both the first sliding groove 330 and the second sliding groove 331 are formed on the base seat 33, and the base seat 33 is rightly fitted in the rectangular space 141. In such manner, it is needless to design another module to couple with the ejecting mechanisms. So a simple, convenient assembly process is achieved, accordingly, to save cost. On the other hand, the base seat 33 allows more ejecting mechanisms to be designed thereon, but do not take additional room as before. Besides, the first mechanism 6 and the second mechanism 5 are covered by the first shell 14 completely avoiding to being disposed out thereof and being interfered by other device.
In this embodiment of present invention, the card connector 1 is structured by vertically stacking two connectors that receive different cards. In another embodiment, a card connector is constructed by at least three connectors for receiving at least three cards, and one connector is designed as the first card connector 10 described above with at least two ejecting mechanisms mounted on a base seat 33 thereof, and the other two connectors are stacked vertically on opposite sides of said connector. The ejecting mechanisms protrude into corresponding card slot upwardly or downwardly to engaging with cards. Such structure also reduces overall size of the card connector, and save more space. In a third embodiment, a card connector comprises two card connectors arranged in a transverse direction or in a level, and two ejecting mechanisms are placed on a base seat formed between the two connectors, particularly, one of the connector should be designed with a card slot that has a L-space receiving space and a rectangular space, and the base seat is rightly received in the rectangular space to couple with ejecting mechanisms.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
